SPECIFICATION forming part of Letters Patent No. 636,879, dated November 14, 1899.

Application filed May 26, 1899. Serial No. 718.370. (N0 model-) To all whom it may concern:

Be it known that I, HENRY E. WILLER, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Screen Frames or the Like, of which the following is a description, reference being-had to the accompanying drawings, which are a part of this specification.

My invention has relation to improvements in screen-frames or the like,the invention possessing particular utility in reference to those frames known as sliding frames.

Heretofore difficulty has been experienced in properly fitting and adjusting screenframes to window-frames. A form of screenframe has been provided wherein a deep groove is formed in one of the side edges thereof, in which groove are placed bowed springs, which latter are adapted to bear against the bead of the window-jamb. This groove is made deeper than the width of the bead, so that the frame can be moved toward the bead when sufficient force is applied to overcome the tension of the spring. The movement provided for is such that the opposite bead is permitted to disengage the more shallow groove in the opposite edge of the screen-frame, so that said frame can be then swung out. This construction of course also provides for readily adjusting the frame to place. When adjusted to place, however, it has been found in practice that there are in many instances gaps or spaces left between the shallow-grooved molding and the bead. Another form of construction has been adopted wherein in the deep groove is placed a bowed spring or springs, while one of the flanges of the shallow groove is made wider than the opposite flange of said shallow groove, the wider flange being of such width that while the frame can be moved edgewise, yet said flange will at all times overlap the bead and close the space between the same and the screen-frame and at the same time prevent the screen-frame from being accidentally forced out of the window-frame, and in this shallow groove is arranged so-called justifying devices or shoes, in connection with means for positively'adjusting said devices so that if the window-frame is not true one of the shoes may be forced outwardly and, if necessary, the other shoe drawn inwardly. This device, it will be understood, contemplates the placing of the bowed springs in one of the grooves and justifying devices separate from the springs in the opposite groove.

The primary object of my invention is to obtain all the desirable features of the lastreferred-to construction in a device wherein the justifying devices and the springs are combined and placed in the deep groove of the screen-frame, the ad justabili ty of the justifying device and the tension of the spring being regulated automatically.

With the above primary object in view the invention consists of the devices and parts or their equivalents, as hereinafter more fully set forth.

In the accompanying drawings, Figure lisa front elevation of a screen-frame adjusted to the outside of a window-frame and showing my attachments properly applied, parts being broken away for clearness of illustration. Fig. 2 is a horizontal section through Fig. 1. Fig. 3 is a detail longitudinal sectional view of one of the shoes. Fig. 4 is an end view of said shoe; and Fig. 5 is a fragment of the screen-frame, showing the pivoted button.

Referring to the drawings, the numeral 5 indicates a Wall or side of a building provided with an ordinary form of window-frame 6, the side jambs thereof provided with the usual heads 7 7.

The numeral 8 indicates a frame, preferably, and as shown in the accompanying illustration of the invention, a sliding screenframe. This frame is shown as provided on one side edge with a longitudinal groove 9, which the head 7 is adapted to fit. This groove is deeper than the width of the bead, so that the screen-frame can be moved edgewise toward the bead. In its opposite side edge the screen frame is provided with a flange 10, which overlaps the bead 7. The edge of the screen-frame where the flange 10 is located has pivoted thereto a button or buttons 18, two being preferably employed. (See Figs. 1, 2, and 5.) These buttons fit in depressions 19, formed in the screen-frame, and the pivot of each button consists of a screw 20, the head of the screw fitting in a central depression in the button. From this central depression extends a straight recess or slot 21. Vhen the screen-frame is in place, the buttons are turned so as to project outwardly, as shown in the drawings, whereby the head 7' is confined between the flange 10 and the buttons and the screen-frame thereby held in place. The buttons are held in their adjusted position by tightening the pivot-screws. WVhenever it is desired to remove the screenframe, the pivot-screws are loosened and the buttons turned into the depressions 19, so as not to project outwardly. The turning of the buttons is readily accomplished by placing a screw-driver or other tool in the recess or slot 21.

In the groove 9 are fitted two of the improved attachments. Both of these attachments are of similar form and consist of a main portion 11, to which is attached at any suitable or desirable point, by means of a rivet 12 or other desirable means, an outwardly-bowed spring 13, the free end of said spring passing through a slot 14 in the base of the shoe, the spring bearing against the inner edge of the outer cross-piece 15, formed by the slot 14. Each shoe is shown as provided with two side pieces 16 16, which advisably gradually increase in width in the direction of the bow of the spring. The shoes are shown as disposed in the groove 9, and one end of each shoe (the end opposite to the end through which the spring protrudes) is pivoted to the inner wall of said groove by means of a screw 17 or equivalent. It willbe noticed that the screw is not turned inwardly to its full extent, (see Fig. 3,) wherebyaslight play of the end of the shoe beneath the head of the screw is permitted in order to provide a pivot or for the outward swinging of the free end of the shoe. The shoes are preferably, although not neceesarily, arranged so that the lower shoe will have its end through which the spring protrudes pointing downward and the upper shoe in such position as to have its end through which the spring protrudes pointing upward. When the shoes are secured as described and the screenframe properlyadj usted to the window-frame, the side flanges 16 of the shoes will receive therebetween the bead 7 of the window-frame with the bowed portions of the springs bearing against the edge of said bead. The extremity of each spring will also bear against the inner wall of the groove 9, and in order to prevent the sharp edge of this extremity of the spring from hearing against the inner wall of the groove said extremity is preferably reversely curved slightly, as clearly shown in Figs. 1 and 3. hen the screenframe is properly adjusted, the opposite bead 7 of the window-frame fits between the flange 10 and the buttons 18.

From the above description of the construction of my invention it will be evident that when the window-frame is not true or has irregularities therein the shoes will automatically compensate for such irregularities, and the screen-frame will therefore fit nicely to the window-frame notwithstanding such irregularities and will also be capable of sliding freely. itself holds the free end of the shoe outwardly, so that the sides of said shoe will embrace the bead '7, inasmuch as the extremity of the free end of each spring is constantly contacting with the inner wall of the groove 9. The free end of the shoe is more positively held outwardly by providing for the spring bearing against the edge of the cross'piece 15. The bow of the spring acting against the bead 7 also creates a constant tension on the spring, which tension will necessarily automatically adjust itself to any variations in the windowframe and will also adapt the screen-frame to be held constantly out in position to which it may be adjusted.

IVhile I have herein shown and described certain details of construction, yet I do not wish to be understood as restricting myself thereto, inasmuch as modifications and variations may be made without departing from the spirit and scope of my invention. For instance, the particular and special form of shoe shown is not absolutely necessary, and any desirable form, in combination with a bowed spring, which will accomplish the same function as that described in reference to these parts is deemed by me to be comprehended by my invention. It is also not absolutely necessary that the combined shoe and spring need be located in a groove in the edge of the sash, as the groove may be omitted and merely an outer flange provided of sufiicient width to overlap the bead of the windowframe. Furthermore, if desired, the slot let may extend entirely through the free end of the bottom of the shoe and the cross-piece 15 be thereby omitted. This cross-piece, however, is advantageously employed, inasmuch as by the engagement of the bowed spring therewith the free end of the shoe is more positively held outwardly.

IVhile I have described my invention with particular reference to screen-frames, yet I wish to be understood as claiming the same in connection with any form of frame in windows or otherwise Where the attachments may be found useful.

While I have herein shown and described the buttons 18, yet it is obvious that these buttons may be omitted and a groove formed in the edge of the screen-frame to receive the bead 7', one of the flanges of said groove be= ing made wider than the other.

IVhat I claim as my invention is- 1. A combined justifying and yielding device for screen-frames, or the like, consisting of a justifying member and a bowed spring secured to the justifying member, said spring having its free end protruding laterally beyond the base or bottom of said justifying member.
